Just before every Olympics, looming doubt starts to surface. Are the cities ready? Has the host country accepted its geopolitical consequences? Will people come?

But this year’s games are especially troubled, and with the opening ceremonies less than 100 days away, the call to cancel Rio’s Summer Olympics has reached a fever pitch. Should Rio just walk away now? Some are saying yes. Here are some of the best reasons why.

26. Poop suits aren’t enough

The special antimicrobial racing suits being designed for rowers to compete in shit-filled water? Probably won’t work.

25. Human body parts on the beach

24. Even Stephen Colbert agrees

23. Zika

Golf is being played at the Games for the first time in 112 years. But the world’s top-ranked golfer, Jason Day, will not go to Rio due to Zika. In a statement he mentioned his “concerns about the possible transmission of the Zika virus and the potential risks that it may present to my wife’s future pregnancies and to future members of our family,” even though the CDC has said Zika is not a long-term problem for couples who are planning on having children in the future.

22. It will be hard to test for doping

The only lab that’s accredited to test athletes’ blood and urine in Brazil has been shut down, according to Deadspin. The World Anti-Doping Agency claimed there will be workaround procedures in place, but since the problem with another doping scandal was that samples were tainted, this could open the door for lots more doping.

19. Superbugs

18. Rio is basically a police state

Concerns about crime and political unrest have transformed Rio into a high-tech surveillance wonderland of security cameras and smartphone sniffers, as Motherboard reports in this really creepy story.

17. Journalists are backing out

It’s not just athletes who are wary about Zika. Now a “handful” of NBC staffers have refused to travel to Rio, including Today anchor Savannah Guthrie, who is pregnant.

16. Athletes are backing out

The first US athlete to withdraw from the games due to Zika is cyclist Tejay van Gardener, who is concerned about transmitting Zika to his pregnant wife. A handful of other athletes have cited Zika as a reason they’re not going.

15. Bankruptcy

Tecnosolo, the construction company in charge of the velodrome, has declared bankruptcy and now another firm is scrambling to complete the $43 million structure by August 11.

14. Violence

A gold medalist sailor from Spain and two other members of the team were robbed at gunpoint. Muggings have become a concern with security budgets slashed.

8. Political scandals

Brazil’s president has been suspended after being impeached (although somereports say she’s being unfairly targeted by political enemies). But that’s not all! More than half of the members of Brazil’s senate are also being investigated for crimes.
